IMPROVEMENT IN PUMPS.

The Schedule referred to in there Letters Patent and making part of the same'.

I, EDsoN LAMPHEAR, of Stepney, in the county of Fairfield, in the State of Connecticut, have invented certain Imp'rovemcnts in Pumps; and I' do hereby declare that the following is a full and exact description thereof'.

My pump is intended to serve as a submerged pump, and isconstructed with reference to conveniently placing and holding it in the bottom of wells or tanks, and in analogous positions, where it will be operated by rods descending from suitable mechanism above.

I will first describe what I consider the best means of carrying out my invention, and will afterwards designate the points which I'believe to he new.

The accompanying drawings form a part of' this specification.

Figure 1 is a vertical section through the body of the pump, and side elevation of the connected parts above and below.

'l Figure2 is a plan View of the working-parts, the delivery-pipe being represented as broken off or eut across horizontally.

Figure 3 is a horizontal section through the vbodyof the pump. v d

Similar letters of reference indicate like parts in all the figures.

I construct the pump with two cylinders, and with two pistons working therein, both delivering they water into a common discharge-pipe.

The cylinders are east together, and I provide novel means of forming an air-chamber in the top of each,

for securing the upper box in each, without endangering the leakage of the air, and for supporting the pump in position by taking hold of the earth below.

I take in the water through very liberal openings at the bottom, so that my pump will'v continue to perform successfully when -thewater is very low.

Referring to the figuresm A* A2 are the cylinders, cast together, as represented. I shall refer to these collectively as the casting A.

M is a winged foot, mounted on stems' m, which are adj usted in sockets in the casting A by means of the screws m, as shown-in iig. 3.

Bl B2 are pistons, fitting snugly without packing within their respective cylinders, and provided with openings through their bodies, and with coveringvalves bl b2, as represented.

C1 C? are piston-rods, provided with adjustable connections cl c, as represented, by which their lengths may be adjusted properly.

D is a lever turning upon vided with a socket, to receive a hand-lever not .represented, by which the lever D may be rocked and the pivot d, and pro-A the pistons Bl B2 reciprocated up and down, as will beobvious.

El E"l are the fixed valves.

They are mounted near the upper portion of each` cylinder', and are provided with apertures, and with covering-valves el e2, which have liberty to play up and down to a moderate extent, as represented.

lIhe play of these valves is limited by an intepnal lip or reinforce, G, cast on the under side of the top of each cylinder.

The holes within these reinforces GrA in the tops of the cylinders are larger than the piston-rods which play through them and allow space for the insertion of a suiiieiently stout sleeve, H, which is cast or otherwise fixed on each of the fixed valves E1 i. It will be understood that `these sleeves are introduced from below.

After they are tightly in place, a screw, h, in each, prevents their' dropping back again.

lIt will now be seen that the fixed valve-seats are held in place by their sleeves H, and screw or pin h; that the reinforces G hold the sleeves H very firmly and tightly, and that they provide an annular space around them, which will serve as an airchamber; and Aif there is any leakage-through the joints in the top of each cylinder, the leakage will be of water-and not of air.

4My pump is very simply constructed, and is easy to keep in order. It requires no packing around either the pistons or the. piston-rods, and vit may endure for an indefinite period without requiring attention.

It will be understood that the delivery-pipe may be connected in any approved manner to the common orifice at the center, and that it may be led up and caused to deliver at one or more points where the water is required.

In introducing my pump in a new well, I adjust the depth of .the foot M below the body of the pump, accordingto the hardness of the sand, clay, mud, or other material which forms the bottom of the well.

In case there is a considerable depth of soft niaterial, it is desirable to adjust the parts, so that the stems rmf, and consequently the footl M shall standat a considerable depth below the bottom of' the cylinders Al A2.

. To avoid the agitation of thebottom materials which might otherwise result from the. active intel'- mittent flow of water between the foot and the bottom of the cylinders, I fix a horizontal plate, N, in the position represented. It may be secured on the rods or stems on., either in a-ixed position or adjustably. n

I claim- 1. The within-described arrangement of theI fixed 3. The foot M and adjust-able stems'fm and shield valves AE1 E2, held in position by means of the sleeves N, arranged to serve relatively to opeubottomed cyl- H surrounding the piston-rod, and secured by the iuder or cylinders of a. submerged pump, 'as specified.

' pins Il., and adapted to serve relatively to the cyliu- In testimony whereof I have signed my name to deis Al A2, pistons Bl B2, :md piston-rods G1 C, as this specilication before two subscribing witnesses. herein set forth. EDSON LAMPHEAR.

2. In combination with the above-named elements, the air-chambers formed in the top of the cylinders Witnesses: A1A2 by the aid of the reinforces G, for the purposes LAURA A. HUBBELL, specified. Y E. SHURrEs.
